Abstract

Se divulga un ensamble para moldear un artículo compuesto que incluye un núcleo de espuma y una capa. El ensamble incluye un molde. El molde tiene una superficie interior y define al menos parcialmente una cavidad, uno o más puertos de descarga de gas, y uno o más elementos de retención. Cada uno de dichos uno o más puertos de descarga de gas tiene una abertura de paso en comunicación de fluido con la cavidad del molde. El ensamble incluye además uno o más elementos de sellado acoplados de manera movible con el molde. Cada uno de dichos uno o más elementos de sellado incluye una cabeza y está configurada para acoplarse al elemento de retención en el molde en una posición ventilada. Además, cada uno de dichos uno o más elementos de sellado corresponde con cada uno de dichos uno o más puertos de descarga de gas.
